So earlier i went to the grocery store and bought my lunch before rushing back home to prepare to head out but on the way down the escalator, this old man and his granddaughter was standing side by side on the escalator. so, i went to the right side (people stand on the left in my country and walk up or down the escalator on the right) where the old man was standing and gently told him excuse me and all he did was to shrug off and proceeded to ignore me. so being petty and in a pretty bad mood today, as soon as i had open pathways, i purposely bumped into him and then proceeded to ignore him as he was calling me. AITAH in this case or he got what he deserved?
